Asking About: Mustang Ford Racing 4.10 Gears (79-10) 7.5


3.9l v6 2004 4.10

Would I need a new/aftermarket clutch if I get 4.10 gears? And does anyone know the torque increase?

Accepted Answer
If your current or stock clutch is good and strong it should be just fine. An aftermarket clutch is always a good upgrade though.

As for your other question a ratio change will not increase produced torque. It will increase the mechanical advantage of the rear end. Therefore it feels like the car is producing more torque. It also gets the engine into it's powerband quicker.
